DETAILED DESCRIPTION OF THE INVENTION

The preparation of heterocyclic sulfonylureas of Formula I can be accomplished using a wide variety of methods well known in the art. The most general methods used to prepare these materials are described below in Equations 1 to 3.

Many heterocyclic sulfonamides of Formula I can be prepared by the coupling reaction of sulfonyl isocyanates of Formula II with heterocyclic amines of Formula III as shown below in Equation 1.

EQUATION 1 ##STR19## wherein

W, R, J, A and I are as previously defined.

A solution of sulfonyl isocyanate of Formula II in a suitable solvent such as methylene chloride, chloroform, dioxane, benzene, toluene, or xylene is added to the heterocyclic amine of Formula III containing a catalytic amount of a suitable base such as diazobicyclo[2.2.2]octane (DABCO) in the same solvent. The reaction is conducted at temperatures ranging from 0° C. to 80° C. and requires from 1 hr. to 48 hrs. When the reaction is complete, as judged by TLC, the product is usually isolated using one of three methods.

Often the desired product precipitates from the reaction mixture can be obtained in pure form by simple filtration. In those cases where the desired product does not precipitate from solution, the reaction mixture is concentrated and the crude product is triturated with an appropriate solvent such as 1-chlorobutane of diethyl ether and the desired product is obtained in pure form by filtration. Alternatively, pure product can be obtained by chromatography on silica gel.

Sulfonyl isocyanates of Formula II can be prepared from methods well known in the art. For a few representative examples see: U.S. Pat. No. 4,238,621; Ulrich and Sayigh, Newer Methods of Preparative Organic Chemistry, Vol. VI, pp. 223-241, Academic Press, New York and London, W. Foerst, Ed.; Japanese Patent No. 76,126,816; U.S. Pat. No. 4,394,506; and K. Kartke, Arch. Pharm., 299, 174 (1966).

Sulfonyl isocyanates of Formula II can also be generated in situ from the corresponding sulfonyl chloride in Formula IV by the action of tetraalkylammonium isocyanate salts. When this reaction is conducted in the presence of heterocyclic amines of Formula III, sulfonylureas of Formula I are produced as shown below in Equation 2.

Equation 2 ##STR20## wherein:

R, J, A and I are as previously defined.

This reaction is best carried out by adding over one to six hours a solution of at least one equivalent of a tetraalkylammonium isocyanate, such as tetra-n-butylammonium isocyanate, in a suitable aprotic solvent, such as dichloromethane or tetrahydrofuran, to a mixture of sulfonyl chloride of Formula IV and heterocyclic amine of Formula III in the same solvent. The reaction is conducted at temperatures ranging from 20° C. to 40° C. When the reaction is complete, as judged by TLC, the mixture is diluted with dichloromethane, washed with 1N sulfuric acid, and dried over sodium sulfate. The mixture is concentrated to furnish the desired product of Formula I in crude form. The crude product can be purified as already described in Equation 1.

Heterocyclic sulfonamides of Formula I can be prepared by the reaction of N-substituted carbamate derivatives of sulfonamides of Formula V with heterocyclic amines of Formula III. This method as well as a general procedure for the preparation of sulfonyl carbamates is taught in U.S. Pat. No. 4,443,245.

Heterocyclic sulfonamides of Formula I can be prepared by the reaction of sulfonamides of Formula V with phenyl carbamates of Formula VI in the presence of a nonnucleophilic base. This general method is shown below (Equation 3a) and is taught in EPO Publication No. 44807. Alternatively, heterocyclic sulfonamides of Formula I can be prepared by the reaction of N-t-butyldimethyl silyl derivatives of sulfonamides of Formula V and phenyl carbamates of Formula VI in the presence of tetra-n-butyl ammonium fluoride as taught in U.S. Pat. No. 4,666,501 (Equation 3b).

Equation 3 ##STR21## wherein:

R, J, A and I are as previously defined.

Phenyl carbamates of Formula VI can be prepared from the corresponding amines of Formula III by methods, or modifications thereof known to one skilled in the art. Some representative methods are described in South African patent application 825671 and South African patent application 825045.

Sulfonyl chlorides of Formula IV can be prepared using a variety of methods well known in the art. Some representative methods are described in: H. T. Clarke et al., Org. Synth. Coll., Vol. 1, 2nd Ed. 1941, p. 85; H. L. Yale and F. Sowinski, J. Org. Chem. 25, 1824 (1960); and H. Meerwein et al., Chem. Ber., 90. 841 (1957).

Sulfonamides of Formula V can be prepared directly from sulfonyl chlorides of Formula IV using methods well known in the art. For reviews, see F. Hawking and J. S. Lawrence, "The Sulfonamides." H. K. Lewis and Co., London, 1950 and E. H. Northey, "The Sulfonamides and Allied Compounds," Reinbold Publishing corp., New York, 1948.

There are a variety of methods in the literature for the preparation of sulfonyl chlorides of Formula IV and sulfonamides of Formula V and the following references are suggested for further details: U.S. Pat Nos. 4,169,719; 4,127,405; 4,349,506; 4,310,346; 4,435,205; 4,420,325; 4,441,910; 4,398,939; 4,481,028; 4,456,469; 4,370,479; and EPO Publication Nos. 23,422; 83,975; 13,480; and 95,925.

Heterocyclic amines of Formula III can be prepared using the procedures described in Equations 4 and 5.

Heterocyclic amines of Formula III can be prepared from the corresponding haloheterocyclic amine of Formula VI via the scheme shown in Equation 4. The halogen group in heterocyclic amines of Formula VI is displaced by activated enolate derivatives of Formula VII to furnish the substitution product of Formula VIII. The t-butyl ester moiety of compounds of Formula VIII can then be decarboxylated under mildly acidic conditions to furnish heterocyclic amines of Formula III.

Equation 4 ##STR22## wherein:

R, R_(a), R_(c) and A are as previously defined and R_(b) is H, CH₃, F, SCH₃ or OCH₃, and

U is ##STR23##

L₁ is Cl, Br of I;

M is X or L₁ ;

Z, Y₁, Y, and X are as previously defined; and

Ua is ##STR24##

M is L₁, or X, R_(b) is H, CH₃, F, SCH₃ or OCH₃ ; and

R_(a), R_(c), X, Y₁, Y, and Z are as previously defined.

The reaction is best carried out by adding active methylene compounds of Formula VIII (which are well known in the art) to a suitable base such as sodium or patassium hydride in a polar aprotic solvent such as N,N-dimethylformamide at temperatures ranging from 0° C. to 15° C. for reaction times of 1 to 8 hours. When the formation of the anion is complete, the haloheterocyclic amine of Formula VI is added either batchwise or in a suitable solvent such as N,N-dimethylformamide. The mixture is allowed to stirr at temperatures ranging from 25° C. to 120° C. for reaction times of 1 to 48 hours. When the reaction is complete, as judged by TLC, the mixture is poured onto a mixture of ice and water and acidified to pH 3-4 using concentrated HCl. In some cases, the product precipitates from solution upon acidification and in these cases, simple filtration furnishes pure heterocyclic amines of Formula VIII. In those cases where the product does not precipitate it is isolated by extraction into ethyl acetate or diethyl ether. Pure heterocyclic amines of Formula VIII can be obtained by column chromatography on silica gel.

The conversion of heterocyclic amines of Formula VIII to the desired heterocycles of Formula III is best carried out by adding the heterocylcic amine of Formula VIII to a solution of an appropriate acid such as trifluoroacetic acid or p-toluenesulfonic acid in an inert solvent such as methylene chloride or benzene at temperatures ranging from 0° C. to 80° C. The reaction is allowed to proceed for from 1 to 48 hours. When the reaction is complete as judge by TLC the mixture is cooled and in some cases the pure heterocyclic amines of Formula III are collected by filtration. In other cases, the reaction mixture is concentrated and the reaction mixture is neutralized using aqueous sodium bicarbonate and the desired product is extracted into an appropriate solvent such as ethyl acetate. The organic layer is dried over sodium sulfate and concentrated to furnish the crude product. Heterocyclic amines of Formula III can be obtained in pure form either by trituration with a suitable solvent such as 1-chlorobutane or diethyl ether or by column chromatography on silica gel.

Alternatively, for heterocyclic amines of Formula VIIIa the t-butyl ester group can be removed by the action of chlorotrimethylsilane and sodium iodide in hot acetonitrile as shown in Equation 5.

Equation 5 ##STR25## wherein:

R is previously defined and

Ua₁ is ##STR26##

Ub is ##STR27## wherein:

R_(b) is H, CH₃, F, or SCH₃ and Y═CH₂ ;

M₁ is Cl, Br, I, H, CH₃, CH₂ CH₃, or SCH₃ ; and

Z is as previously defined.

This is best done by adding an excess of chlorotrimethylsilane to a stirring solution of the hetetocyclic amine of Formula III containing from a catalytic amount up to a full equivalent of sodium iodide. The mixture is stirred at temperatures ranging from 0° C. to 82° C. for reaction times of 1 hour to 48 hours. When the reaction is complete as judged by TLC, the mixture is filtered and the filtrate is dissolved in a suitable solvent such as ethyl acetate and washed with water and brine and dried. Pure heterocyclic amines of Formula VIII are then obtained by trituration of chromatography as described above in Equation 4.

Those heterocyclic amines of Formula III where R_(b) is other than hydrogen or methoxy can be prepared from the intermediate heterocyclic amines of Formula VIII (where R_(b) is hydrogen). In those cases the intermediate amine of Formula VIII is first deprotonated with base and subsequently treated with an appropriate electrophile to yield, after treatment with mild acid, the desired substituted heterocyclic amines of Formula III (Equation 6).

Equation 6 ##STR28## wherein:

M is L₁ or X, and Rb is H, CH₃, Cl, Br or SCH₃ ;

E⁺ is CH₃ I, Cl₂, Br₂, CH₃ --S--SCH₃ or ClSCH₃ ; and

R₁, R_(a), R_(c), L₁, X, Ua and A are as previously defined.

This reaction is best carried out by adding the heterocyclic amine of Formula VIII (where R_(b) is hydrogen) in an appropriate solvent such as N,N-dimethylformamide, dimethylsufloxide or tetrahydrofuran to a suitable base such as sodium or potassium hydride, potassium t-butoxide, or sodium methoxide in the same solvent at a temperature ranging from 0° C. to 50° C. for from 1 to 48 hours. To the anion is added dropwise the appropriate electrophile either in the same solvent or neat at a temperature ranging from 0° C. to 50° C. for 1 to 48 hours and the reaction is allowed to proceed until it is deemed complete as judged by TLC. The reaction mixture is poured onto ice water and the product is isolated by filtration if it is a solid or by extraction into an appropriate solvent such as ethyl acetate or diethyl ether. Heterocycles of Formula VIII can then be isolated in pure from by trituration or column chromatography on silica gel in the same general manner described in Equation 1. The procedure for cleaving the t-butyl ester group in these compounds is the same as described above in Equation 4.

Heterocyclic amines of Formula III where A is A-1 can be prepared from the heterocyclic amines in Formula VIII where Ub is Ub-1 and L₁ is Cl, Br or I. For these compounds the heterocyclic amine of Formula VIII is treated with the appropriate alkoxide or mercaptide ion using methods well known in the art.

Formulations

Useful formulations of the compounds of Formula I can be prepared in conventional ways. They include dusts, granules, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates and the like. Many of these may be applied directly. Sprayable formulations can be extended in suitable media and used at spray volumes of from a few liters to several hundred liters per hectare. High strength compositions are primarily used as intermediates for further formulation. The formulations, broadly, contain about 0.1% to 99% by weight of active ingredient(s) and at least one of (a) about 0.1% to 20% surfactant(s) and (b) about 1% to 99.9% solid or liquid diluent(s). More specifically, they will contain these ingredients in the following approximate proportions:

Lower or higher levels of active ingredient can, of course, be present depending on the intended use and the physical properties of the compound. Higher ratios of surfactant to active ingredient are sometimes desirable, and are achieved by incorporation into the formulation or by tank mixing.

Typical solid diluents are described in Watkins, et al., "Handbook of Insecticide Dust Diluents and Carriers", 2nd Ed., Dorland Books, Caldwell, New Jersey, but other solids, either mined or manufactured, may be used. The more absorptive diluents are preferred for wettable powders and the denser ones for dusts. Typical liquid diluents and solvents are described in Marsden, "Solvents Guide," 2nd Ed., Interscience, New York, 1950. Solubility under 0.1% is preferred for suspension concentrates; solution concentrates are preferably stable against phase separation at 0° C. "McCutcheon's Detergents and Emulsifiers Annual", MC Publishing Corp., Ridgewood, N.J., as well as Sisely and Wood, "Encyclopedia of Surface Active Agents", Chemical Publishing Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foaming, caking, corrosion, microbiological growth, etc.

The methods of making such compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer or fluid energy mill. Suspensions are prepared by wet milling (see, for example, Littler, U.S. Pat. No. 3,060,084). Granules and pellets may be made by spraying the active material upon preformed granular carriers or by agglomeration techniques. See J. E. Browning, "Agglomeration", Chemical Engineering, Dec. 4, 1967, pp. 147ff. and "Perry's Chemical Engineer's Handbook", 5th Ed., McGraw-Hill, New York, 1973, pp. 8-57ff.

Utility

Test results indicate that the compounds of the present invention are highly active preemergent or postemergent herbicides or plant growth regulants. Many of them have utility for broad-spectrum pre- and or post-emergence weed control in areas where complete control of all vegetation is desired, such as around fuel storage tanks, industrial storage areas, parking lots, drive-in theaters, around billboards, highway and railroad structures. Some of the compounds have utility for selective weed control in crops such as wheat, barley, rice, corn and cotton. Alternatively, the subject compounds are useful to modity plant growth.

The rate of application for the compounds of the invention are determined by a number of factors, including their use as plant growth modifiers or as herbicides, the crop species involved, the types of weeds to be controlled, weather and climate, formulations selected, mode of application, amount of foliage present, etc. In general terms, the subject compounds should be applied at levels of around 0.05 to 5 kg/ha, the lower rates being suggested for use on lighter soils and/or those having a low organic matter content, for selective weed control or for situations where only short-term persistence is required, such as a herbicide for fallow land.

The compounds of the invention may be used in combination with any other commercial herbicide; examples of which are those of the triazine, triazole, uracil, urea, amide, diphenylether, carbamate and bipyridylium types.

The herbicidal properties of the subject compounds were discovered in a number of greenhouse tests. The test procedures and results follow.

Test A

Seeds of crabgrass (Digitaria sp.), barnyard-grass (Echinochloa crus-galli), giant foxtail (Setaria faberi), wild oats (Avena fatua), velvetleaf (Abutilon theophrasti), morningglory (Ipomoea spp.), cocklebur (Xanthium pensylvanicum), sorghum, corn, soybean, surgarbeet, cotton, rice, wheat, barley and purple nutsedge (Cyperus rotundus) tubers and optionally cheatgrass (Bromus secalinus) and downy brome (Bromus tectorum) were planted and treated preemergence with the test chemicals dissolved in a non-phytotoxic solvent. At the same time, these crop and weed species were treated with a soil/foliage application. At the time of treatment, the plants ranged in height from 2 to 18 cm. Treated plants and controls were maintained in a greenhouse for sixteen days, whereupon all species were compared to controls and visually rate for response to treatment. The ratings are based on a numerical scale extending from 0=no injury, to 10=complete kill. The accompanying descriptive symbols have the following meanings:

C=chlorosis or necrosis;

B=burn

D=defoliation

E=emergence inhibition;

G=growth retardation;

H=formative effects;

U=unusual pigmentation

X=axillary stimulation; and

S=albinism

6Y=abscised buds or flowers.

Test B Postemergence

Three round pans (25 cm diameter by 122.5 cm deep) were filled with Sassafrass sandy loam soil. One pan was planted with nutsedge (Cyperus rotundus) tubers, crabgrass (Digitaria sanguinalis), sicklepod (Cassia obtusifolia), jimsonweed (Datura stramonium), velvetleaf (Abutilon theophrasti), lambsquarters (Chenopodium album), rice (Oryza sativa), and prickly sida (Sida spinosa). The second pot was planted with green foxtail (Setaria viridis), cocklebur (Xanthium pensylvanicum), morningglory (Ipomoea hederacea), cotton (Gossypium hirsutum), johnsongrass (Sorghum halepense), barnyardgrass (Echinochloa crus-galli), corn (Zea mays), soybean (Glycine max), and giant foxtail (Setaria faberi). The third pot was planted with wheat (Tricticum aestivum), barley (Hordeum vulgare), wild buckwheat (Polygonum convolvulus L.), downy brome (Bromus tectorum), sugarbeet (Beta vulgaris), wild oat (Avena fatua L.), common chickweed (Stellaria media), blackgrass (Alopercurus myosuroides), and rape (Brassica napus). The plants were grown for approximately fourteen days, then sprayed postemergence with the chemicals dissoled in a non-phytotoxic solvent.

Preemergence

Three round pans (25 cm diameter by 12.5 cm deep) were filled with Sassafras sandy loam soil. One pan was planted with nutsedge tubers, crabgrass, sicklepod, jimsonweed, velvtleaf, lambsquarters, rice, and teaweed. The second pot was planted with green foxtail, cocklebur, morningglory, cotton, johnsongrass, barnyardgrass, corn, soybean, and giant foxtail. The third pot was planted with wheat, barley, wild buckwheat, cheatgrass, surgarbeet, wild oat, viola, blackgrass, and rape. The three pans were sprayed preemergence with the chemicals dissolved in a non-phytotoxic solvent.

Treated plants and controls were maintained in the greenhouse for approximately 24 days, then all rated plants were compared to controls and visually rated for plant response.

Response ratings are based on a scale of 0 to 100 where 0=no effect, and 100=complete control. A dash (-) response means no test.

Response ratings are contained in Table B.
